水损坏是公路沥青路面早期损坏的主要原因,而造成这种损坏的关键因素是过大的沥青路面孔隙率。同时,在沥青混合料合成过程中,击实成型受击实温度影响,如低温情况下,沥青混合料流动性较差,增加辗压难度,降低压实度,增加孔隙率,降低混合料性能,进而降低公路路面的使用性能。因此,在不同沥青混合料击实成型过程中,应加强击实温度控制,提高混合料性能。本文主要依据具体沥青混合料成型过程,结合试验数据,分析击实温度对沥青混合料参数的影响,为在公路建设中沥青混合料的科学使用提供参考,提高公路质量。
Water damage is the main cause of early damage to highway asphalt pavement, and the key factor causing such damage is excessive asphalt pavement porosity. In the meantime, in the process of asphalt mixture compaction, the compaction molding temperature is affected by the compacted temperature, such as low fluidity, poor fluidity of the asphalt mixture, difficulty of rolling, reduction of compaction, increase of porosity and decrease of the mixture performance , Thereby reducing the performance of road pavement. Therefore, in the compaction molding of different asphalt mixtures, compaction temperature control should be strengthened to improve the performance of the mixture. Based on the concrete asphalt mixture forming process and the experimental data, the paper analyzes the effect of compaction temperature on the parameters of asphalt mixture, and provides a reference for the scientific use of asphalt mixture in highway construction and improves the highway quality.
